Radiometry for Nighttime Sub-Cloud Imaging of Venus' Surface in the Near-InfraRed Spectrum
Brian M. Sutin, Anthony B. Davis, Kevin H. Baines +2
Does radiometry (e.g., signal-to-noise ratio) limit the performance of near-IR subcloud imaging of our sister planet's surface at night? It does not. We compute subcloud radiometry…
Imaging Venus' surface at night in the near-IR from above its clouds: New analytical models for the effective spatial resolution, illustrated with new Parker Solar Probe data
Anthony B. Davis
There are a handful of spectral windows in the near-IR through which we can see down to Venus' surface on the night side of the planet. The surface of our sister planet has thus be…
GEOSCAN: Global Earth Observation using Swarm of Coordinated Autonomous Nanosats
Changrak Choi, Anthony B. Davis
The climate crisis we are facing calls for significant improvements in our understanding of natural phenomena, with clouds being identified as a dominant source of uncertainty. To…
Moments of Sunlight Pathlength in Water and Aerosol Clouds from O Spectroscopy: Exploitable Parameter Sensitivities
Anthony B. Davis, Quentin Libois, Nicolas Ferlay +1
The last IPCC assessment states that clouds and aerosols remain a challenge in climate prediction with Global Climate Models. Therefore, NASA's 2017 Decadal Survey has made them, a…
Toward Cloud Tomography from Space using MISR and MODIS: The Physics of Image Formation for Opaque Convective Clouds
Anthony B. Davis, Linda Forster, David J. Diner +1
3D convective cloud images form via two intertwined radiative diffusion processes. Sunlight starts in the anti-solar direction and ends in toward-sensor ones, but repeated forward-…
Multi-view polarimetric scattering cloud tomography and retrieval of droplet size
Aviad Levis, Yoav Y. Schechner, Anthony B. Davis +1
Tomography aims to recover a three-dimensional (3D) density map of a medium or an object. In medical imaging, it is extensively used for diagnostics via X-ray computed tomography (…
Cloud Tomography from Space using MISR and MODIS: Locating the "Veiled Core" in Opaque Convective Clouds
Linda Forster, Anthony B. Davis, David J. Diner +1
For passive satellite imagers, current retrievals of cloud optical thickness and effective particle size fail for convective clouds with 3D morphology. Indeed, being based on 1D ra…
Reconstruction of Cloud Geometry from High-Resolution Multi-Angle Images
Guillaume Bal, JiaMing Chen, Anthony Davis
We consider the reconstruction of the interface of compact, connected "clouds" from satellite or airborne light intensity measurements. In a two dimensional setting, the cloud is m…
An Efficient Approach for Optical Radiative Transfer Tomography using the Spherical Harmonics Discrete Ordinates Method
Aviad Levis, Yoav Y. Schechner, Amit Aides +1
This paper introduces a method to preform optical tomography, using 3D radiative transfer as the forward model. We use an iterative approach predicated on the Spherical Harmonics D…
A Generalized Linear Transport Model for Spatially-Correlated Stochastic Media
Anthony B. Davis, Feng Xu
We formulate a new model for transport in stochastic media with long-range spatial correlations where exponential attenuation (controlling the propagation part of the transport) be…
A Hybrid (Monte-Carlo/Deterministic) Approach for Multi-Dimensional Radiation Transport
Guillaume Bal, Anthony Davis, Ian Langmore
A novel hybrid Monte Carlo transport scheme is demonstrated in a scene with solar illumination, scattering and absorbing 2D atmosphere, a textured reflecting mountain, and a small…
A General Strategy for Physics-Based Model Validation Illustrated with Earthquake Phenomenology, Atmospheric Radiative Transfer, and Computational Fluid Dynamics
Didier Sornette, Anthony B. Davis, James R. Kamm +1
Validation is often defined as the process of determining the degree to which a model is an accurate representation of the real world from the perspective of its intended uses. Val…
Celebrating the Physics in Geophysics
Anthony B. Davis, D. Sornette
As 2005, the International Year of Physics, comes to an end, two physicists working primarily in geophysical research reflect on how geophysics is not an applied physics. Although…
Algorithm for Model Validation: Theory and Applications
D. Sornette, A. B. Davis, K. Ide +3
Validation is often defined as the process of determining the degree to which a model is an accurate representation of the real world from the perspective of its intended uses. Val…
